Sub-GeV Dark Matter Under Pressure from Direct Detection
Andrew Cheek, Pablo Figueroa, Gonzalo Herrera +1
The DAMIC-M collaboration recently reported impressive bounds on sub-GeV dark matter, robustly testing both thermal and non-thermal models for the very first time. In this work we…
Dark photon dark matter from flattened axion potentials
Hong-Yi Zhang, Paola Arias, Andrew Cheek +3
Dark photons can be resonantly produced in the early universe via their coupling to an oscillating axion field. However, this mechanism typically requires large axion--dark photon…
Axion Dark Matter Archaeology with Primordial Gravitational Waves
Andrew Cheek, Anish Ghoshal, Debarun Paul
We investigate the complementary information to be gained from inflationary gravitational wave (IGW) signals and searches for QCD axion dark matter. We focus on post-inflationary P…
Testing the dark origin of neutrino masses with oscillation experiments
Andrew Cheek, Luca Visinelli, Hong-Yi Zhang
The origin of neutrino masses remains unknown to date. One popular idea involves interactions between neutrinos and ultralight dark matter, described as fields or particles with ma…
